GB 4806 Testing for Plastic Water Bottles
Testing Overview
Plastic water bottles fall under the scope of the GB 4806.7 standard for plastic products intended for food contact. Components such as the bottle body, sealing rings, printing inks, and adhesives are tested separately as homogeneous materials.
Basic Test Items: Sensory requirements, overall migration, potassium permanganate consumption, heavy metals (lead), and colorfastness (decolorization test).
Material-Specific Items: For PC (polycarbonate) bottles, Bisphenol A (BPA) is a key focus. For PET, PP, and Tritan materials, specific migration tests are conducted based on the material type. If the product features color printing, the inks are also tested. Migration tests are performed using food simulants—such as 4% acetic acid and 10% ethanol—under conditions that reflect the product's intended temperature range. The resulting test report can be used for domestic e-commerce, retail distribution, and regulatory spot checks.
Required Documentation
1. Testing application form, specifying the material of the bottle body (PP/PC/Tritan/PET), maximum operating temperature, and whether it is suitable for hot liquids.
2. Bill of Materials (BOM): A list of materials used for the bottle body, sealing rings, inks, and adhesives.
3. Samples: 3–5 finished units of the same model. Different colors or formulations must be submitted as separate samples.
4. Product photographs, label information, and user instructions.
Testing Process
1. Submit documentation; an engineer will evaluate the materials and usage conditions to determine the required test items and provide a quote.
2. Confirm the service agreement, complete payment, and ship samples to the laboratory.
3. The laboratory prepares the samples and conducts migration testing using standardized food simulants.
4. Upon passing, a GB 4806 test report bearing CMA and CNAS marks is issued. If the product fails, guidance on raw material adjustments is provided, followed by retesting.
5. Any changes to the raw materials of the bottle body, sealing rings, inks, or formulations require retesting.
6. Companies should retain a Declaration of Conformity and documentation regarding raw materials for potential regulatory inspections.
Timeline and Notes
Standard turnaround time is 5–7 business days; expedited service (2–3 business days) is also available.
Note: If the outer plastic casing of a water bottle does not come into contact with the liquid, it is not subject to GB 4806 testing. Only components that have direct contact with drinking water require testing.
